Superconducting qubit

The Team

The Superconducting qubit team at NQCP is headed by Associate Professor Morten Kjaergaard who is the Principal Investigator of the Superconducting Quantum Information Devices Lab (SQuID Lab), a research team jointly at NQCP and Center for Quantum Devices also at Niels Bohr Institute. The superconducting qubit team is focused on developing extensible control-, validation- and error-mitigation techniques for superconducting qubits towards the goal of realizing logical qubits. The team is also focused on developing and implementing small scale quantum algorithms and protocols related to fundamental quantum information physics which can help shed light on next-generation quantum processors and their potential applications.

In collaboration with the other teams at NQCP and in partnership with other research groups at NBI and beyond, the superconducting qubit team aims to push our understanding and applicability of superconducting qubits. Finally, in very close partnership with Quantum Foundry, the superconducting qubit team aims to develop next-generation fabrication and materials techniques for high coherence superconducting qubits. 

Key partners and satellites

The team collaborates frequently with other research groups and partners exploring superconducting qubit development for quantum information applications. These collaboration include the Engineering Quantum Systems group at MIT (https://equs.mit.edu/) (led by Prof. Will Oliver), as well as the Andersen Lab at TU Delft (https://qutech.nl/lab/andersen-lab/), (led by Prof. Christian Andersen), and Gyenis Lab at CU Boulder (led by Prof. Andras Gyenis).

Protected qubit encodings and novel qubit couplers

As part of the superconducting qubit platform we are also exploring protected qubit encodings, new qubit coupling mechanisms and new gate implementations. In particular we are working on developing multi-qubit coupling elements based Josephson Ring Modulators, hybrid superconductor/semiconductor based Josephson junctions for novel qubit-qubit coupling and parity protected qubit encodings.
